Description

Lens and mold transfer system {LENS AND MOLD TRANSFER SYSTEM}

The present invention relates to a system for transferring a lens and a mold by being connected to a lens molding machine that molds the imported lens raw material into a three-dimensional shape and then carries it out.

Recently, digital cameras, camera phones, web cameras, etc. have become smaller and thinner, and the size of the camera module is gradually decreasing. As the camera module is miniaturized, the demand for aspherical lenses instead of the conventional spherical lenses is greatly increasing.

Such aspherical lenses may be produced by a grinding method or a press molding method, but the grinding method is unsuitable for mass production. Therefore, recently, a press molding method in which raw materials are put into the upper core and the lower core, and the upper core and the lower core are assembled to each other, and then introduced into a lens molding machine, is formed through a high-temperature heating process, a pressing process, and a cooling process.

The lens and mold transfer system is connected to the lens molding machine so that the above processes can be performed continuously. The lens and mold transfer system is formed to take out the mold from the lens molding machine, load the molded lens, and insert the raw lens material for molding into the mold, and then re-insert the mold into the lens molding machine.

The lens molding machine and the lens and mold transfer system connected thereto constitute a lens molding system that produces aspherical lenses. Therefore, the cycle time of the lens and mold transfer system affects the cycle time of the lens forming system. Accordingly, there is a need for a study on a system that quickly transfers lenses and molds with more efficient copper lines.

The lens and mold transfer system is configured to separate the mold taken out from the lens molding machine, take out the molded lens, and then insert the raw lens material into the separated mold. Therefore, it can be said that reducing the time required to take out the molded lens and input the lens raw material is one factor that can reduce the cycle time of the lens molding system.

On the other hand, when the mold is removed to take out the molded lens, the lens is usually mounted on the lower core, but in some cases, the lens may be attached to the upper core. As such, there is a need for research on a technology capable of preventing the molded lens from being attached to the upper core, and taking out the molded lens even if it is attached to the upper core.

In addition, in a mold having a plurality of cavities so as to mold a plurality of lenses at once, the upper core must be separated at the correct position of each cavity, the molded lens is taken out, the lens raw material is injected, and the upper core is reassembled. However, since there is an assembly tolerance between the upper core and the lower core in each cavity, and a plurality of cavities are provided in one mold, if the correct position is not aligned, there is a high possibility of a molding defect.

In addition, when the mold is removed for taking out the molded lens, if a large load is applied to the mold, there is a risk that the molded lens located between the upper core and the lower core is broken. Therefore, there is a need for research on a technology that prevents a large load from being applied to the mold during the separation.

On the other hand, the mold carried out from a specific lens molding machine may be placed in a state rotated at a certain angle (eg, 180 degrees) based on when it is carried into the lens molding machine. In this case, the lens and mold transfer system should be introduced into the lens molding machine by rotating the mold at a predetermined angle so that the mold is brought into the lens molding machine, that is, the original position. Therefore, it is necessary to study a technique for rotating the mold at an appropriate timing during the transfer process of the mold.

In addition, the mold may be transported in a pick-up method or a slide method. In the case of the slide transfer method, there is a problem that it is difficult to connect the structures in which the mold slides horizontally without a step, and if the mold is slide-transferred in a downward slope, the height difference between the part where the mold is finally carried into the lens molding machine occurs. There is a problem. Therefore, when the mold is transported in a slide manner, research on a technology capable of solving the above-described problem is required.

The effects of the present invention obtained through the above-described solution are as follows.

First, since the lens raw material conveying unit is formed to move to the third position together with the molded lens conveying unit in a state in which the raw lens material is picked up, the raw lens material can be injected immediately after the molded lens is taken out. Accordingly, the cycle time of the lens and mold transfer system can be reduced, and as a result, the molding speed of the aspherical lens can be improved.

Second, before the upper core is picked up by the upper core pick-up unit, since the mold is configured to apply vibration to the transfer table through which the mold is slid, the molded lens attached to the upper core may be separated by the vibration. In addition, since the molded lens transfer unit includes a first molded lens transfer module for adsorbing the molded lens attached to the upper core and a second molded lens transfer module for adsorbing the molded lens seated on the lower core, Even if attached, the molded lens may be taken out by the first molded lens transfer module.

Third, before the upper core is separated, the mold centering part fixes the mold body of the mold and presses the upper core and the lower core through a hole communicating with the cavity of the mold body to center the upper core at the correct position of each cavity. Separation, removal of the molded lens, input of raw material for the lens, and reassembly of the upper core can be performed. Therefore, the problem of molding defects caused by not being able to match the exact position can be solved.

Fourth, since the balance weight is formed to pull the moving member of the upper core pickup unit upward, the load applied to the upper core when the suction unit of the upper core pickup unit contacts the upper core can be reduced. Accordingly, the possibility of damage to the molded lens when the mold is removed for taking out the molded lens may be reduced.

Fifth, the mold discharged from the lens molding machine is rotated at a first angle (for example, +90 degrees) by the first rotating unit before being transferred to the upper core pickup part, and the mold passing through the upper core pickup part is taken out of the mold. Because the mold is rotated at a second angle (for example, +90 degrees) by the second rotation unit before being transferred to the part, the mold will be brought into the lens molding machine in the original position (180 degrees + 90 degrees + 90 degrees = 360 degrees). I can.

Sixth, a height correction unit is disposed between the horizontal seating surface of the transfer table disposed at the rear end and the seating surface of the mold discharging unit, and is configured to move up and down to compensate for the height difference between them, so that a new mold slide transport structure can be implemented. .

10 is a perspective view showing a plurality of transfer tables 122 shown in FIG. 3, and FIG. 11 is a perspective view of the mold transfer unit 123 shown in FIG. 3.

Referring to FIG. 10, a plurality of transfer tables 122 are arranged along the X-axis direction in the drawing between a first position (A) and a second position (B), so that the mold 10 is seated and transported by slide. Is formed. Each of the plurality of transfer tables 122 has a horizontal seating surface 122 ′.

The other transfer table 122 so that the mold 10 can be slidably transferred from one transfer table 122 to the other transfer table 122 adjacent thereto along the +X axis direction in the drawing. The horizontal seating surface 122 ′ of is preferably disposed at the same height as the horizontal seating surface 122 ′ of any one of the transfer tables 122, or slightly lower than that. For example, the plurality of transfer tables 122 may be arranged so that the height of the horizontal seating surfaces 122 ′ gradually decreases finely along the +X-axis direction in the drawing.

In addition, a downwardly inclined inclined portion 122" may be formed on the side surfaces of the two transfer tables 122 arranged to face each other. When the lens molding system is operated for a long time, a plurality of transfer tables may be caused by external factors. Since the height of 122 is slightly twisted, the horizontal seating surface 122 ′ of the other transfer table 122 described above is finer than the horizontal seating surface 122 ′ of any one transfer table 122 described above. In this case, when the inclined portion 122" of the other transfer table 122 guides the transfer of the mold 10, the inclined portion 122" is not provided. It is made to prevent impact that may be applied to the mold 10 and the molded lens or the raw material of the lens.

Referring to FIG. 11, the mold transfer unit 123 is formed to slide the mold 10 along the +X-axis direction on the plurality of transfer tables 122.

In this drawing, it is shown that the mold transfer unit 123 is configured to be movable along the X-axis direction and the Y-axis direction on the drawing. Specifically, the mold transfer unit 123 includes a first guide rail 123a, a first moving member 123b, a second guide rail 123c, a second moving member 123d, and a clamping unit 123e. .

The first guide rail 123a extends along the X-axis direction in the drawing, and the first moving member 123b is installed on the first guide rail 123a to slide along the first guide rail 123a.

The second guide rail 123c is mounted on the first moving member 123b and extends along the Y-axis direction in the drawing. The second moving member 123b is installed on the second guide rail 123c to slide along the second guide rail 123c.

The clamping unit 123e is installed on the second moving member 123d to clamp the mold 10. The clamping unit 123e includes two clamping arms 123f that are disposed to face each other and are formed to adjust the distance between them. Each clamping arm (123f) may be provided with a roller (123g) that is formed to be inserted into the groove (11b) formed on both sides of the mold (10).

When clamping the mold 10, the second moving member 123d is moved along the -Y-axis direction in the drawing, and the two clamping arms 123f are moved to be close to each other with the mold 10 interposed therebetween. It is made to clamp (10) from both sides. At this time, the roller 123g is inserted into the groove 11b so that the mold 10 can be clamped at the correct position. For example, even if the mold 10 is clamped at a slightly twisted position, the roller 123g is moved along the rounded groove 11b of the mold 10, so that the clamping arm 123f moves the mold 10 in place. So that it can be clamped in.

When the mold 10 is unclamped, the two clamping arms 123f are separated from both sides of the mold 10, and the second moving member 113d is moved along the +Y-axis direction. It is arranged so as to deviate from the transport path.

Referring back to FIG. 10, during the process of slide-transferring the mold 10 on the plurality of transfer tables 122 by the mold transfer unit 123, vibration is applied to the mold 10 by the vibration module 122f. All.

In this drawing, it is shown that the vibration module 122f is installed under the one 122b so as to vibrate the horizontal seating surface 122' of the one 122b. The vibration module 122f may be formed to apply vibration to the central portion 122g of any one of the above 122b.

When the mold 10 is transferred to any one of the above 122b, the vibration module 122f is driven to vibrate the horizontal seating surface 122'. Accordingly, vibration is transmitted to the mold 10 seated on the horizontal seating surface 122 ′, and the lens molded by the vibration can be separated from the lower core 14 and the upper core 15.

At this time, the mold transfer unit 123 may place the mold 10 in the central portion 122g of the mold 10, and after the mold 10 is positioned, the two clamping arms 123f It may be formed to be moved away from both sides of (10) to unclamp the mold (10). This is to prevent vibration from being transmitted to the mold transfer unit 123.

When vibration is applied to any one 122b, the two transfer tables 122a and 122c are not transmitted to the two transfer tables 122a and 122c disposed on both sides of the one 122b. It is preferable to be spaced apart from any one (122b) at a predetermined interval. In the above arrangement, the two transfer tables 122a and 122c and the horizontal seating surfaces 122 ′ of any one 122b so that the mold 10 can be slid and transferred while seated on the transfer tables 122. ) May be arranged such that the height gradually decreases along the +X-axis direction on the drawing.

When the driving of the vibration module 122f is stopped, the two clamping arms 123f are moved to be close to the mold 10 to clamp the mold 10, and the first moving member 123b is in the +X axis direction in the drawing. Is made to go.

Thereafter, the mold 10 is moved to a third position C between the first position A and the second position B and undergoes a process of separating the upper core 15 for taking out the molded lens. In the case of separating the upper core 15 to take out the molded lens from the mold 10, the molded lens is usually mounted on the lower core 14, but in some cases, the molded lens is attached to the upper core 15. May be attached.

However, as described above, when vibration is applied to the mold 10 by the vibration module 122f during the process of moving from the first position (A) to the third position (C), the molded lens is moved to the upper core 15 ) Is separated from the core 14 and the above-described problem can be solved.

Hereinafter, a process of separating the upper core 15 will be described.

When the mold 10 is transferred to the transfer table 122d corresponding to the third position C among the plurality of transfer tables 122 by the mold transfer unit 123, the mold 10 is transferred by the adsorption module (not shown). (10) is fixed, and then the upper core 15 and the lower core 14 are centered by the mold centering unit 130, and the upper core 15 is then upper sided by the upper core pickup unit 140 It is made to be moved to and separated.

Specifically, an adsorption hole 122h is formed in the transfer table 122d corresponding to the third position C among the plurality of transfer tables 122, and an adsorption module is installed below the adsorption hole 122h. The adsorption module is formed to suck air around the adsorption hole 122h through the adsorption hole 122h.

The adsorption holes 122h may be disposed at the center of the transfer table 122 corresponding to the third position C, and may be provided in plural. In this drawing, when the mold 10 is disposed in the center of the transfer table 122 corresponding to the third position C, a plurality of adsorption holes 122h are vertically placed in the cavity 11a of the mold 10. It is shown that it is formed to overlap in the direction.

When the mold transfer unit 123 places the mold 10 in the center of the transfer table 122 corresponding to the third position C, the adsorption module is driven to adsorb the mold 10. When the mold 10 is fixed by adsorption, the two clamping arms 123f of the mold transfer unit 123 are away from both sides of the mold 10, and the second moving member 123d is +Y in the drawing. It is moved along the axial direction so that the mold centering unit 130 to be described later clamps the mold 10 to perform centering.

12 is a perspective view showing the mold centering unit 130 shown in FIG. 1, and FIG. 13 is a view for explaining a concept in which the mold 10 is centered by the mold centering unit 130 of FIG. 12.

As in the present invention, when a mold 10 having a plurality of cavities 11a is used, the inner sleeve 13, the upper core 15 and the lower core 14 are assembled in each cavity 11a. If the tolerance is not controlled, the process of separating the upper core 15, taking out the molded lens, inserting the lens raw material, and reassembling the upper core 15 is not performed accurately, thereby increasing the probability of occurrence of defects.

Therefore, in order to control the above-described tolerance, the components disposed inside each of the cavities 11a, that is, the inner sleeve 13, the upper core 15, and the lower core 14 must be centered.

12 and 13, the mold centering part 130 fixes the mold body 11 of the mold 10 at the third position C, and the hole 11c communicates with the inside of the mold body 11. ) Through the upper core 15 and the lower core 14 is formed to be centered in a manner of pressing.

Specifically, the mold centering part 130 includes a guide rail 131, a moving member 132, a first arm 133 and a second arm 134.

The guide rail 131 extends along the Y-axis direction in the drawing, and the moving member 132 is installed on the guide rail 131 so as to slide along the guide rail 131.

The first and second arms 133 and 134 are installed on the moving member 132 to clamp and center the mold 10. The first and second arms 133 and 134 are disposed so as to face each other, and are formed such that a separation distance between them is adjusted.

Each of the first and second arms 133 and 134 has a clamping unit 135 for fixing the mold 10 and a pressing unit for centering the upper core 15 and the lower core 14 of the mold 10 ( 136).

When the mold 10 is fixed to the center of the transfer table 122d corresponding to the third position C by the adsorption module, the moving member 132 is moved along the +Y axis direction in the drawing. By this movement, the first and second arms 133 and 134 are disposed on both sides with the mold 10 interposed therebetween.

Thereafter, the first and second arms 133 and 134 are moved to be close to each other, clamping the mold 10 from both sides, and centering the upper core 15 and the lower core 14 at the same time.

Specifically, the clamping unit 135 is inserted into the grooves 11b formed on both sides of the mold body 11 of the mold 10, and is formed to clamp the mold 10 at the correct position. The clamping unit 135 may be formed of a roller so as to be in rolling contact with the rounded groove 11b. In this case, even if the mold 10 is clamped at a slightly twisted position, the roller is moved along the rounded groove 11b of the mold 10, so that the first and second arms 133 and 134 Allows clamping in place.

In addition, the pressing unit 136 is inserted into the holes 11c formed on both sides of the above-described groove 11b and is formed to center the upper core 15 and the lower core 14 in a pressing manner. In the mold structure having the inner sleeve 13 described in FIGS. 4 to 6 above, the pressing unit 136 is inserted into the hole 11c to press the inner sleeve 13. According to the pressure, the inner sleeve 13 and the upper core 15 and the lower core 14 inserted in the inner sleeve 13 contact the inner wall of the cavity 11a.

Specifically, the inner sleeve 13 is in contact with the inner wall of the cavity 11a facing the hole 11c. The inner sleeve 13 is in line contact with the inner wall, and a portion in line contact is opposite to the hole 11c. In this way, as the inner sleeve 13 is centered to a preset position, between the upper core 15 and the lower core 14 inserted into the inner sleeve 13, and the upper core 15 and the lower core 14 Centering of the arranged molded lenses is made.

The pressing units 136 are provided on both sides of the clamping unit 135, respectively. The clamping unit 135 may be composed of a pressing pin. At this time, the pressure pin is configured to elastically press the inner sleeve 13, and may be configured to reduce a load applied to the inner sleeve 13.

According to the above-described mold centering part 130, the inner sleeve 13, the upper core 15, and the lower core 14 assembled in each cavity 11a are centered to separate the upper core 15 to be described later. And, the process of taking out the molded lens, inputting the raw material of the lens, and reassembling the upper core 15 can be accurately performed. Therefore, the problem of molding defects caused by not being able to match the exact position can be solved.

14 and 15 are perspective views of the upper core pickup unit 140 shown in FIG. 2 viewed from different directions.

Referring to FIGS. 14 and 15 together with FIG. 3, the upper core pickup unit 140 is a transfer path of the mold 10 at a third position C between the first position A and the second position B. It is arranged to overlap with. The upper core pickup unit 140 is configured to pick up the upper core 15 for taking out the molded lens in a state in which the upper core 15 and the lower core 14 are centered by the mold centering unit 130.

The upper core pickup unit 140 is configured to adsorb the upper portion of the upper core 15 and lift it in the +Z-axis direction in the drawing. To this end, the upper core pickup unit 140 includes a driving unit 141, a moving member 142, and an adsorption unit 143.

The driving unit 141 is arranged in the vertical direction, that is, in the Z-axis direction in the drawing, so that the length thereof is variable. For example, the drive unit 141 may be an electric cylinder.

The moving member 142 is connected to the driving unit 141 and is formed to be movable up and down, that is, in the Z-axis direction in the drawing by the driving of the driving unit 141. In this drawing, the moving member 142 is disposed on one side of the driving unit 141, and the structure is interlocked with a portion in which the length of the driving unit 141 is variable by the connecting member 145.

In addition, the upper core pickup unit 140 may further include a guide rail 146 so that the vertical movement of the moving member 142 can be guided.

The guide rail 146 is disposed vertically, that is, in the Z-axis direction in the drawing. In this figure, it is shown that the guide rail 146 is installed in the fixed box 147.

The moving member 142 is installed on the guide rail 146 and is formed to slide along the guide rail 146.

The adsorption unit 143 is installed under the moving member 142 and is formed to adsorb the upper core 15. The adsorption unit 143 is provided in a number corresponding to the upper core 15, and is arranged to overlap on each upper core 15 when each upper core 15 is centered by the mold centering unit 130 do.

The adsorption unit 143 includes a body 143a and an adsorption sucker 143b.

The body 143a has a pillar shape having a hollow portion and is formed of a rigid material.

The suction sucker 143b is formed of a soft material, is disposed in the hollow part of the body 143b, and contacts the upper part of the upper core 15 by suction.

When the adsorption unit 143 is in contact with the upper core 15, if a large load is applied to the upper core 15, there is a risk of breaking the molded lens located between the upper core 15 and the lower core 14. . Accordingly, the following technique is applied to the present invention so as to reduce the load applied to the upper core 15 when the adsorption unit 143 contacts the upper core 15.

First, when the adsorption unit 143 contacts the upper core 15, the weight of the moving member 142 may affect the load applied to the upper core 15. In view of this, a balance weight 144 formed to pull the moving member 142 upward is connected to the moving member 142 through a wire 149.

Specifically, the wire 149 is connected to the moving member 142 and the balance weight 144, respectively, and the wire 149 is at least one fixed pulley disposed on the moving member 142 and the balance weight 144 It is formed to be wound around (148a, 148b). That is, the moving member 142 and the balance weight 144 are arranged in a suspended form by the wire 149. Accordingly, the balance weight 144 is formed to apply a force upward to the moving member 142.

In this drawing, it is shown that the first fixed pulley 148a is disposed on the moving member 142 and the second fixed pulley 148b is disposed on the balance weight 144.

The first and second fixing pulleys 148a and 148b may be installed in the above-described fixing box 147. In this case, a receiving portion 147a in which at least a part of the balance weight 144 is accommodated may be formed on one side of the fixed box 147 in which the balance weight 144 is disposed.

It is preferable that the weight of the balance weight 144 is greater than the weight of the moving member 142. For example, the weight of the balance weight 144 may have a weight obtained by adding the weight of the adsorption unit 143 to the weight of the moving member 142, or may have a greater weight.

By adjusting the weight of the balance weight 144, when the adsorption unit 143 contacts the upper core 15, the load applied to the upper core 15 may be almost zero. That is, the adsorption unit 143 may be configured to contact the upper core 15 without load.

As described above, since the balance weight 144 is formed to pull the moving member 142 of the upper core pickup unit 140 upward, the adsorption unit 143 of the upper core pickup unit 140 is the upper core 15 The load applied to the upper core 15 when contacting the) may be reduced. Therefore, when the mold 10 is separated for taking out the molded lens, the possibility of damage to the molded lens may be reduced.

In addition, the end of the suction sucker (143b) is disposed to protrude downward from the end of the body (143a). Accordingly, when the suction sucker 143b adsorbs the upper part of the upper core 15, the upper core 15 contacts the end of the body 143a even if the suction sucker 143b of a soft material is contracted and moves upward. Even if it is not or is in contact, the load applied to the upper core 15 may be minimized.

16 is a perspective view showing the height correction unit 124 shown in FIG. 3.

As described above, so that the mold 10 can be slidably transferred from one transfer table 122 to another transfer table 122 adjacent thereto along the +X-axis direction in the drawing, the other one It is preferable that the horizontal seating surface 122' of the transfer table 122 is disposed at the same height as the horizontal seating surface 122' of any one of the transfer tables 122, or slightly lower than that. However, considering that it is practically difficult to arrange all of the plurality of transfer tables 122 at exactly the same height, the horizontal seating surface 122 ′ of the transfer table 122e disposed at the rear end is disposed at the front end. It is disposed lower than the horizontal seating surface 122 ′ of the transfer table 122.

By the way, the height of the seating surface 1 on which the mold 10 is seated on the side of the mold carrying part 112 for carrying out the mold 10 to the lens molding machine is the horizontal seating surface 122' of the transfer table 122e disposed at the rear end. ) Compared to In consideration of this, between the horizontal seating surface 122 ′ of the transfer table 122e disposed at the rear end and the seating surface 1 of the mold discharging unit 112, the upper and lower portions, that is, Z in the drawing, to compensate for the height difference between them. A height correction unit 124 configured to be movable in the axial direction is disposed.

When the mold 10 is seated, the height correction unit 124 is made to rise so as to match the height with the seating surface 1 of the mold discharging unit 112 located at the second position B.

Thereafter, when the mold 10 is slid and transferred to the mold carrying part 112, the height correction part 124 is made to descend to be disposed lower than the horizontal seating surface 122' of the transfer table 122 at the rear end. That is, the next mold 10, which is transferred to the horizontal seating surface 122 ′ of the transfer table 122 at the rear end, is formed to lower the height so that it can be slid and transferred to the height correction unit 124.

By adjusting the height by the above-described height correction unit 124, the mold 10 is a transfer table 122e disposed at the rear end in a slide manner, the upper surface of the height correction unit 124, and the mold carrying unit 112 side. It can be sequentially transferred onto the seating surface (1) of.

Specifically, the mold 10 seated on the transfer table 122e disposed at the rear end is a height correction unit ( 124).

Then, the height correction unit 124, before the mold 10 seated on the upper surface is clamped by the second rotation unit 126 to be described later, the seating surface 1 and the height located at the second position (B). It is formed to rise to fit. In this case, the upper surface of the height correction unit 124 may form the same plane as the seating surface 1 or may be disposed higher than the seating surface 1.

Next, the mold 10 is clamped by the second rotating unit 126 and rotated at a second angle (for example, +90 degrees) while seated on the upper surface of the height correction unit 124, and then the mold is taken out. The slide is transferred to the seating surface (1) of the part (112).

Thereafter, the height correction unit 124 is formed to be lowered so that the upper surface forms the same plane as the horizontal seating surface 122 ′ of the transfer table 122e disposed at the rear end, or is disposed lower than the horizontal seating surface 122 ′. do.

In this drawing, it is shown that the height correction unit 124 includes a support member 124a, a guide member 124b, a moving member 124c, and a seating member 124d.

The support member 124a is disposed vertically.

The guide member 124b is mounted on the support member 124a and includes a guide rail extending in the Z-axis direction in the drawing.

The moving member 124c is coupled to the guide member 124b so as to be movable in the Z-axis direction along the guide rail. The guide member 124b or the moving member 124c is mounted or connected to a driving module that provides a driving force so as to move relative to the guide member 124b.

The seating member 124d is coupled to the moving member 124b and disposed horizontally so that the mold 10 is seated. The upper surface of the seating member 124d corresponds to the upper surface of the height correction unit 124 described above.

17 is a perspective view showing the second rotation unit 126 shown in FIG. 3.

In some cases, the mold 10 carried out from a specific lens molding machine may be rotated at a certain angle (eg, +180 degrees) based on the time it is carried into the lens molding machine. In this case, the lens and mold transfer system 100 moves the mold 10 to the same state as when the mold 10 is brought into the lens molding machine, that is, at an original position, at a predetermined angle (eg, +180 degrees or- 180 degrees) and put into the lens molding machine.
